My guess is that on resume from S3 root PD needs to be again mapped to CPU
address space. Maybe changing the patch according to Christian's advise will
be enough. I will take a look tomorrow. Or it has to do with the resume failure
you are experiencing. What ASIC are you using ? I also tested with gfx8 ASIC
and haven't observed any issues with resume. Did you update the firmware for
this ASIC to latest #
